A new drone technology has revolutionised the transport of building materials in southwestern China, significantly boosting efficiency and cutting costs.

The video was filmed in Nujiang Lisu Autonomous Prefecture in Yunnan Province on 13th June. Drones gracefully lifted off, laden with bags of cement on a construction site. These drones swiftly soared over treacherous gorges, delivering their payload to the opposite side in mere minutes.

Historically, the transportation of construction materials in the Nujiang region has been a daunting challenge due to its isolated location and rugged terrain. Workers traditionally relied on labour-intensive methods, such as carrying materials on their backs or using pack animals, to traverse the difficult landscape. These methods were not only time-consuming and strenuous but also prohibitively expensive.

A site manager highlighted the remarkable advantages of drone transport. The process, previously requiring up to six hours and significant manpower for a single bag of materials, can now be accomplished effortlessly by drones, drastically reducing both time and labour costs.

This innovation has brought immense convenience to construction projects in the region.

云南怒江傈僳族自治州，一个地理环境复杂的西南偏远地区，近日迎来了一项运输技术的革新。工人们开始采用无人机运输水泥等建筑材料，这一创新举措极大地提升了运输效率，降低了成本。

在过去，由于地理位置偏远且地形复杂，云南怒江地区的建筑材料运输一直是一个难题。工人们往往需要依靠人背马驮的方式，跋山涉水地将建筑材料运送至施工地点，这不仅耗时耗力，而且成本高昂。然而，随着科技的不断进步，无人机技术的引入为这一难题提供了全新的解决方案。

视频显示，一建筑工地上，随着一架架无人机的缓缓起飞。一袋袋的水泥迅速飞越峡谷，准确地将货物送达对岸，整个过程仅用了几分钟。

据工地负责人介绍，无人机运输不仅快速高效，而且大幅降低了运输成本。以前，运送一袋建筑材料可能需要五六个小时，耗费大量时间和人力，而现在，无人机能够轻松完成这一任务，为工地带来了极大的便利。
